The Project Gantt control is used to display data in a task-oriented Gantt chart. The Project
Gantt control is consists of a menu bar, a tool bar, a TreeTable on the left that is capable of
displaying hierarchical data, a chart on the right that displays task bars, and a legend.

Gantt Model

The Project Gantt component uses a model to access the data in the underlying list. The specific
model class is org.apache.myfaces.trinidad.model.TreeModel.

Column

The immediate children of a Project Gantt component. Each visibleColumn component creates a
separate column in the left hand side TreeTable. For more information see the documentation for

Time Axis

The Project Gantt control requires a major and a minor time axis. You can specify them by adding
a timeAxis component using a facet named "major" and a facet named "minor" as a child of the Gantt.

Sorting

The Project Gantt component supports sorting columns in ascending or descending order in the exact same
way as the Table and TreeTable components. Please refer to the documentation
for these components for details on sorting.
